1、Talkwalkers Blue Silk GPT for consumer intelligence:New way of generating insightsBlue Silk AI white paperThe first breakthrough in AI was in the computer vision field thanks to the appearance of CNN models 2(Convolutional Neural Network),the use of backward propagation techniques3 and most importan

2、tly,larger datasets,and training those models on GPU(Graphical Processing Units)cards.In 2012,during the ImageNet Large Scale Visual Recognition Challenge,the AlexNet 4 model,combining all the above methods,drastically reduced the top-5 error rate to 15.3%,more than 10 percent lower than the other m

3、odels in the competition.In the following years,with each improvement in the architecture such as new activation functions 5 or batch normalization 6 layers,the modern state-of-the-art CNN models exceeded human performance and recently surpassed the top-5 error rate with an astonishing 99%accuracy l
